TECHNICAL FIELD

The present disclosure relates to the field of image capture and, more particularly, to an image capture assembly and an aerial photographing aerial vehicle containing the image capture assembly.

BACKGROUND

An image capture assembly, e.g., a terminal apparatus, such as a camera, a video camera, or a surveillance camera, carried by an unmanned aerial vehicle (UAV), or a unit arranged in a terminal apparatus for obtaining images, usually includes a lens component and a circuit board coupled to the lens component. The circuit board is generally provided with a plurality of functional circuits for implementing different functions, such as an image sensing circuit, a photoelectric conversion circuit, an image processing circuit, an image transmission circuit, a power supply circuit, a control circuit, and/or the like.

As the image capture assembly becomes more compact and miniaturized, an integration level of the functional circuits is getting higher. That is, the functional circuits need to be integrated in a relatively small and confined space in the image capture assembly. Correspondingly, heat generated by the functional circuits is often difficult to dissipate. As the heat builds up to a certain degree, performance of the functional circuits is degraded, and thus overall performance of the image capture assembly is degraded. Damage to the image capture assembly may occur in some situation. Correspondingly, photographing performance of the aerial photographing aerial vehicle that carries the image capture assembly is also be degraded.

SUMMARY

In accordance with the disclosure, there is provided an image capture assembly. The image capture assembly includes a heat-conducting housing, a camera component in the heat-conducting housing, a circuit board adapter, and a heat-conducting sheet. The circuit board adapter is in the heat-conducting housing and electrically coupled to the camera component. The heat-conducting sheet is attached to the camera component and arranged between the camera component and the heat-conducting housing to conduct heat generated by the camera component to the heat-conducting housing.

Also in accordance with the disclosure, there is provided an image capture assembly. The image capture assembly includes a heat-conducting housing, a camera component in the heat-conducting housing, a circuit board adapter, and a heat-conducting filler. The circuit board adapter is in the heat-conducting housing and electrically coupled to the camera component. The heat-conducting filler is filled between the camera component and the circuit board adapter to conduct heat generated by the camera component to the heat-conducting housing through the circuit board adapter.
